My mind being immaterial would not mean it, even partially, operates independent of the laws of nature. Since my mind is a natural thing, it would mean the immaterial is part of the laws of nature.Suppose your mind is immaterial, (at least partially) operating independently of the laws of nature. — Relativist
I certainly agree it's different from the boulder. Because, in this scenario (which I agree with) our minds are not nothing but an incredibly complex expression of the laws of physics.You have chosen a path down the mountain, but you might have taken a different path if you knew it to be more scenic, offering more shade, or if you knew a rattlesnake awaited you on your chosen path. You were, at all times, free to choose a route based on your knowledge, the aesthetic appeal, fears, and your skills. Do you agree this is different from the boulder? — Relativist
In this scenario, there is nothing other than the laws of physics at work. The dominoes fall/the billiard balls bounce around. There is no possibility of anything happening that is not the result of those physical interactions, and the result can only be one exact thing. There is literally no possibility of any other outcome.Now suppose your mind is entirely the product of physical brain function. You have the exact same freedom to choose a route based on your knowledge, the aesthetic appeal, fears, and your skills. In both cases, these factors are the result of events in your life (e.g. the DNA that produced you, your studies, your physical conditioning and mountaineering skills). Why should the fundamental basis of these factors (physical vs immaterial) matter? I don't think it does. You have no more, and no less, freedom. — Relativist
I understand that there are options. But if I chose which path to take when I hiked down a mountain the same way a boulder chose which path to take when it rolled down the mountain - that is, because of physical events (since "minds are purely a consequence of physical brain activity") - and, despite there having been many different routes between top and bottom for each of us, I had no more ability to have taken a different route than the one I took than the boulder had, then "agency" and "intention" are simply feelings we have for the results of physical events that take place in our brains. We call the physical events that take place when an airplane moves through the air flight; the physical events that take place in green plants photosynthesis; the physical events that take place as it rains on a mountain erosion; the physical events that take place as the earth circles the sun orbiting; on and on. The airplane is not even aware that it is flying, much less have feelings about it. Same for the plant, the rain, and and the earth.How is an act intentional if there is no option but to act, and in that exact way?
— Patterner
There ARE options. See my above reply to Gnomon (the bold part). — Relativist
As I was going back and forth between the two doors of Ben & Jerry's in the freezer section at the store today, picking up several and reading the description, considering if I was in the mood for something with peanut butter, or caramel, considering the marshmallow ice cream, etc., it certainly felt like I had a choice then, not merely in hindsight.The illusion is that of hindsight: that we could actually have made a different one. — Relativist
So yes, I believe the antecedent state will necessarily result in the consequent state. — Relativist
In actuality, we could have only made a different choice had there been something different within us (a different set of beliefs, disposltions, impulse...). — Relativist
It seems to me that we could call the physical events that involve rock and snow being pulled down a mountain by gravity an avalanche, the physical events that involve air and water moving In a huge circular pattern a hurricane, and the physical events of bio-electric impulses moving through a brain a choice. They, and every other example we can make, are all entirely the result of the laws of physics that we are familiar with. Their settings and materials are different, but the difference between the setting/material of the human brain and any other setting/material is not more significant than three difference between any other two setting/materials.Sure, but every choice was preceded by some sequence of one or more thoughts. Given that sequence, the resulting choice will follow. — Relativist
Unfortunately, I would have to pay $61 to read that. And that is nothing close to a guarantee I would understand it.Here's what in 2014 Josef Ruckavicka wrote in The American Mathematical Monthly Volume 121, 2014 Issue 6, which goes total the same lines as we have discussed: — ssu
Yes, that is my understanding of LD.If assumed that LD has God-like abilities, that's a different issue. The basic idea didn't start from the entity have other abilities except perfect knowledge of the laws of nature and perfect knowledge of the data about everything. Nowhere is it hinted that LD is in control of everything, the idea is really that the LD can perfectly extrapolate from current data and knowledge what the future will be. — ssu
But a thing with the perceptions and intellect to understand everything, whether or not it interacted with anything, is not a necessary part of an entirely deterministic reality. The fact that there isn't such a thing (someone recently told me why there could not be such a thing on another thread, although I never suspected there was) does not have any bearing on whether or not everything, including everything about us, is deterministic.Yet notice that it's not anymore interacting. LD is then more of a historians ultimate event checker. But the issue of course is settled when LD doesn't interact with the World it's forecasting. But this naturally wasn't at all what Laplace had in mind. We are part of the universe ...and so are our models too. — ssu
Well, naturally, the scientist tested it himself at first. I don't remember all the specifics of the conversation (it's been decades. But I have the paperback, so I'll check.), but I can't imagine he did not try to trick it.And here you see the obvious difference: there is no negative self reference loop. The friend doesn't know the information. As I've not read the book, I think the friend doesn't then say to the scientist "Why don't you do it yourself? Are you going obey and write what the paper says you to, or can you write something else?". How the writer would continue on, would be interesting... — ssu
I think I am finally understanding you. :grin: I don't know if you changed your wording in such a way that I finally caught on, or if I was just too dense to figure it out until now. The latter is certainly a good possibility, and I don't want to embarrass myself by going back and looking at what you were saying before.Just think about it: if this something with the perceptions and intellect to understand everything would now write here what you Patterner will say, how could it get it right? Because before you write you next comment you would read it, think about and comment on it. — ssu
Is it not the proposition of this thread? Some think it is, some think it isn't. Not to say we can prove it one way or thre other. If we could, there wouldn't still be new threads about it.Is everything in this reality deterministic,
— Patterner
I don't think that the idea that everything in this reality is deterministic is an empirical hypothesis. It is a completely different kind of proposition. — Ludwig V
This is what I'm trying to understand about where some of you - you two in particular, at the moment, but others who are not posting in this thread - stand. Is everything in this reality deterministic, and we just don't have the necessary information and intelligence to be able to calculate terribly much, particularly regarding human choices, about the future? Or are some aspects of this reality - notably, human choices - not deterministic? Understandable if anyone does not know which they think is the case.And before he or she thinks that you are attacking the whole idea of determinism, it should be told that the issue in the limitations of modelling that determinism, not the determinism itself!
— ssu
So you are saying that the world is deterministic, even though our models will never demonstrate that? — Ludwig V
I'm basically asking the same thing again. Does ordinary life require a whole different way of thinking in the same sense that we need to think of large numbers of air molecules as thermodynamics, because we simply can't perceive such a gargantuan number, much less calculate all the interactions that will take place between all of them within the space they occupy?That you did make choices isn't relevant for the determinist model: your choosing to throw the pillow is just given.
— ssu
Yes. Physics doesn't have the conceptual apparatus to describe or even acknowledge choices. Ordinary life requires a whole different way of thinking — Ludwig V
Why is that? Whether I chose to write a comment or not, it is a decision. I have perceived what I perceived. It is all converted into bio-electric impulses, neurotransmitters, and what not. Then it all runs to whichever parts of my brain each thing runs to. Parts where memories are stored, parts where logic examines, etc., etc. Then things move towards a decision. Particles collide, neurons fire, structures do their job, action potentials are initiated, etc.You cannot write a comment that you don't write, even if obviously those kind of comments that you don't write do exist. — ssu
Yes, I understand. But why can't how a model takes itself into account be calculated? That's just more input fed into the algorithm.The crucial part here is that modelling the past there's no interaction and the model doesn't have to take itself into account. What has happened has happened. That you did make choices isn't relevant for the determinist model: your choosing to throw the pillow is just given. But you hopefully understand that it's different to model this when it hasn't happened, especially you know about the model before you have thrown it. Then a whole Pandora's box has been opened from the determinist view. — ssu
I believe the idea is that all of our actions are determined by the progressions of arrangements of all the constituents of our brains. Mental states are either identical to, or entirely determined by, brain states. In theory, a more advanced technology could pinpoint all the constituents of our brains, see all the forces acting on them, and calculate future arrangements. Why can that not be logical?If a "fatalistic" determinist argues that this kind of determinism (where all of our reactions can be forecasted) is perhaps possible in the future (as we don't know what the future holds and what kind of technological/scientific advances there are), then one has simply to remind them that this science then simply can't be logical. — ssu
The causes of some events are more complicated than others. The causes of our simplest actions are probably more complicated than the causes of most events. Possibly any event. As I recently said, there are many variables, many kinds of variables, and all of the variables are interacting with at least some of the others. We don't have the ability to track that, much less predict future actions. We barely have the ability to predict future events. (Some people are amazing at pool.) Still, is it not all on the same spectrum?The language-games around actions are unbelievably complicated and very difficult to summarize. The same is not true of events — Ludwig V
You said, "We could not act freely..." What do you mean?Can you give me an example of a free action?"
— Patterner
Tempting. But it wouldn't be a clear case. Almost everything we do can be described as free from some perspectives and not free from others. — Ludwig V
Can you explain the conceptual difference?The question is this: Did I let go of the pillow in exactly the way I did because all the constituents of my brain - whether we examine them as particles and physics, or molecules and chemistry, or structures and biology, or whatever - acted in the only ways each of them could, all purely physical interactions driven by the physical laws?
Did I throw the pillow because all the constituents of my brain acted in the only ways each of them could, all purely physical interactions driven by the physical laws?
— Patterner
The answer to those questions is yes. But the questions are asked in the context of the glass breaking and so lead us to neglect the conceptual difference between the glass breaking (an event) and my throwing the pillow (an action, normally). — Ludwig V
Can you tell me what the definition of our problem is if the answer is Yes?If the answer is Yes, then we are not choosing things any more than the glass is choosing to break exactly as it does, or the debris is choosing to come to rest exactly as it does after an avalanche. We merely have awareness of things that the glass and mountain lack.
— Patterner
So you are an epiphenomenalist?
I don't agree. If the answer is yes, that doesn't justify your conclusion. It defines our problem. If the answer is no, that also doesn't justify any conclusion. It also defines our problem. — Ludwig V
Why is determinism called determinism? What is deterministic about it?Now, does this deterministic view of there being your answer 1038, 1039 and 1050 limit what you can write? No. Could they be forecasted? Again no, this isn't simple extrapolation from what has become for. — ssu
Can you define "freedom"? Freedom from what?Freedom is not opposed to determinism; it requires it. — Ludwig V
Can you give me an example of a free action?We could not act freely if the causal network was not (reasonably) reliable. — Ludwig V
Unlimited determinism is still determinism. That's my point. Many say we can make choices within an entirely deterministic reality. My position is that those choices are equivalent to the glass breaking. Yes, glasses hitting floors can break in in gigantic number of different ways. But every glass that has ever actually hit a floor broke exactly as it did because that's the only way it could have. Because of the speed it was going when it hit, the spin, the exact location that first made contact, the material it and the floor were made of, and many other factors.Does this refute the idea that you let go of the pillow in exactly the way I did because all the constituents of my brain? Actually not. The determinism holds. But it shows that this determinism isn't at all a limit here. — ssu
If I knock a glass off of a table, I do not think it is preordained that it will then fall to the floor and break into pieces. But it will fall to the floor and break into pieces. And, given all the factors, it can only break in one specific way, with x pieces of various sizes and shapes. What I mean is, exactly how it falls determines what part of it hits the floor first, at what angle, at what speed, etc. If it falls without spinning and lands on its base, it will break in one way. (I support it might not break at all in the scenario.) If it spins at a rapid rate, it might land not quite horizontal, with its rim hitting first, and shatter spectacularly. No matter how it hits, even though we don't have the ability to calculate everything the instant before it hits the floor and know how it will break, once it hits, there is only one possible outcome.What is the sham here is thinking that determinism limits your actions or you don't have the ability to choose... because it's somehow preordained, because there is the deterministic future. — ssu
It seems to me that the idea of choices in a deterministic reality is a sham. Sure, it is possible for a human to choose cake over ice cream. But when one of us is actually presented with the two options, if we pick one up because the billion bouncing billiard balls landed that way, and we could not have picked up the other because the balls landed in the only way they could, then how is such a "choice" is of no greater value or interest than is the final arrangement of the rocks and dirt when an avalanche settles?Determinism doesn't say much. It also doesn't limit our choices. — ssu
I guess the idea is common enough. In How to Create a Mind, Ray Kurzweil writes:Thank you for bringing this idea to my attention, Patterner. I really like how a seemingly hopeless situation like uncountable air molecules can – by their motion – actually bear fruit by giving us definitive information… namely temperature. And expanding this idea to “firing neurons” and “thought” is interesting. — Thales
Of course, there is much debate over whether or not consciousness is explained by this physical system.Although chemistry is theoretically based on physics and could be derived entirely from physics, this would be unwieldy and infeasible in practice, so chemistry has established its own rules and models. Similarly, we should be able to deduce the laws of thermodynamics from physics, but once we have a sufficient number of particles to call them a gas rather than simply a bunch of particles, solving equations for the physics of each particle interaction becomes hopeless, whereas the laws of thermodynamics work quite well. Biology likewise has its own rules and models. A single pancreatic islet cell is enormously complicated, especially if we model it at the level of molecules; modeling what a pancreas actually does in terms of regulating levels of insulin and digestive enzymes is considerably less complex. — Kurzweil
We can take that a step further. Knowing what we know about gravity, we cannot fully explain the motion of stars and galaxies. it has been determined that there must be something that we cannot detect in any way, but which has a gravitational effect. It is called dark matter, and the amount of it that exists has been calculated.For some reason, this brings to my mind the principle of “Operationalism,” which gained some popularity among certain logical positivists in the 1920s-30s. It goes something like this: Scientific concepts that lack direct, empirical evidence can be “saved” by linking them to experimental procedures. “Gravitation,” for example, can not be seen, heard, smelled, tasted or touched, but it can nevertheless be determined “operationally” by observing phenomena such as planetary orbits. — Thales
Importantly, thermodynamics did more than merely establish that mean kinetic energy correlated with temperature—it proposed that this is what temperature actually is. — Seth
I guess the Matrix is a simulation to many sentient programs, and VR to many other sentient programs (Smith and Oracle, for example) and humans.The Matrix is also an example of a VR, not an example of the simulation hypothesis. — noAxioms

And they usually fail, it seems to me. The large muscles that are in motion can't be stopped sufficiently by the smaller ones. Still, they are able to try.I assume it takes practice to get very good at that. — punos
Difficulty to test it. If I know I'm on the wrong screen, I don't commit myself in the first place.I'm also sure you can train yourself to be more conscious about taping that icon. It's probably a good idea to at least run that experiment on yourself. See how it goes, and see what you learn. — punos
Yes. If human minds exist because of physics. Or, since the human body, particularly the brain, seems indispensable for the existence of human minds, if they exist solely because of physics.↪Patterner if it doesn't exist because of physics, it exists because of human minds, but human minds exist because of physics, then...
Then human minds aren't fundamental, they exist because of physics, and indirectly those other things exist because of physics too. — flannel jesus
Indeed. Fundamental things are not responsible for books, televisions, the internet, space shuttles, music, automobiles, bombs, poetry, mathematics, and a billion other things we could list. Not one of these things exists because of the laws of physics and properties of particles. They only exist because of human minds. I do not think the sole cause of the world being reshaped so thoroughly, in so many ways, could be not real.I think we need a way for non fundamental things to still be real. Basically. Because WE are non fundamental, and my mind is the most real thing I know. — flannel jesus
